901 transmission cooler, Can it be done on the cheap? Options

[bondo]

I have found small oil coolers with a fan for $100, but the electric pumps are expensive. My plan is to either find a cheap electric pump, or try and use the ring gear as a pump. The tricky part about the second option is it's hard to test. Can a cheap fuel pump be used to pump gear oil?

The intent here is to cool the oil and send it to the upper bearings so my 901 lasts behind a V8.

This is for a daily driver. My engine exceeds the reccomended limit of 300 ft-lbs (it does 325 stock and it may do more without cats). I realize that shock loading will kill it either way, but I've heard of 3rd gear failures from "I don't do burnouts" drivers. I'm actually not that convinced that burnouts kill 901s, as long as you're not on the gas when it hooks up. I want this trans to last a looong time. I figure a cooler will give the best "no bang" for the buck.

The ring gear idea is to use the "point the vent the wrong way and the trans empties itself" idea, but optimized. I have doubts that it would be enough to pump through a cooler though. I don't want to do belt drive, my belt system is already designed and built.

Has anyone with a trans cooler killed a 901? What did it take?
